MEANS FOR TRANSMITTING POWER FROM STEAM-ENGINES OR OTHER MOTORS.

SPECIFICATION forming part of Letters Patent No, 251,593, dated December27, 1881.

. Application filed March 23, 1881. (No model.)

To all whom tt may concern Be it known that I, HENRY A. JAMiEsoN, ofBrooklyn, in the county of Kings and State ot' New York, 4have inventedcertain new and useful Improvements in Means for Transmittin g Powerfrom Steam-Engines or other Motors, ol' which the following is aspecitication.

Myinventiou relates to mechanism for transmitting the power ot` asteam-engine or other motor to any distant point-as, for instance, fromthe top to the bottom otl a mine-shaft for workingpumps to free the mineof water-without the use of rods, shaftiug, belts, gearing, or otherpositive connections.

The object of the invention is to enable watertor other incompressibleliquid to be practically used as a means of transmitting power, thewater or liquid being forced alternately through pipes by thereciprocation of the piston or diaphragm of a steam-engine or othermotor, and actuating a piston or diaphragm in a cylinder or chamber at adistant point.

The invention consists in the combination, with two cylinders orchambers and pistons or diaphragms therein, of two pipes forestablishing a free communication from the two ends of one cylinder orchamber to the two ends ofthe other cylinder or chamber, a steam-engineor other motorfor reciprocating' one of said pistons or diaphragrns, andpass-over valves in the cylinder or chamber of the piston or diaphragmso actuated as to permit the liquid to pass from one end thereof` to theother end, as

hereinafter fully described. When the two cylinders or chambers andtheir connecting-pipesare lled with water or other liquid the movementof one piston or diaphragm will force the water infront of it throughone of the connecting-pipes, and thus produce a simultaneous movementofthe other piston ordiaphragm, and the powerof the actuating piston ordiaphragm, when moved in either direction, is transmitted Vthrough awater or liquid column and prod uces-l a corresponding movement oftheother piston or diaphragm, which may operate a pump or perform otheruseful work. Whenever the piston or diaphragm which is actuated by theliquid completesits stroke the continued motion of the other piston ordiaphragm will cause the liquid to pass through one or the other of saidpass-over valves and permit the last-said piston or diaphragm tocomplete its stroke, thus providing for the working of the two pistonsor diaphragme simultaneously after the completion of lthe first stroke,even though they may not both be at the end ot their stroke whenstarted.

The invention also consists in the combination, with the foregoing, of asupply-reservoir connected with one of the cylinders or chambers or withthe connecting-pipes, and serving to compensate for any leakage bykeeping the two cylinders or chambers and their connectin g-pipescompletely tilled with water or liquid.

In the accompanying drawings, Figure 1 represents a longitudinalelevation and partial section ot' a pumping apparatus embodying myinvention and arranged in a mine-shaft: and Fig. 2 represents atransverse section 'upon the dotted linea-, Fig. l.

Similar letters of reference designate correspondinp,` parts in bothiigures.

A designates a cylinder, which may bc arranged in any suitable place-as,for instance, immediately over the mouth of a mine-shaft, B; and Odesignates a piston, which is reciprocated by a direct-actin g engine,D, of ordinary or any other suitable construction, or by any othermechanism adapted to the situation. The cylinder A is very similar to anordinary pump-cylinder, but is not provided with any suction ordischarge valves.

E designates a cylinder, whichis arranged at the bottom of the shaft B,or in any other situation where it is not desirable to place the engineD itself. Upon opposite ends of the cylinder E are single-acting pump-cylinders F, which openinto the cylinderE and are closed at theirouter ends, as clearly shown. In the cylinder E is a piston, Gr, towhich are connected two pump-plungers, H, and the two plungers andpiston may be provided with suitablelleather or other packings and beall connected by a bolt, a., passing through them and having a uut, b,at each end. In the ends ofthe cylinders F may be placed rubber cushionsb for the nuts b to strike against. Below the cylinder E is asuction-chamber, I, into- Which water is drawn through a suction-pipe,c, and above it is a discharge-chamber, J, from which water isdischarged through a standpipe, d, which may lead to the top of theshaft` f IOO l. Water is drawn from the suction-chamber through valves einto the pump-cylinders F, nd from said pump-cylinders is dischargedhrough other valves, j', into the dischargehamber J; but none of thewater enters the ylinder E.

The combination, with the cylinder E and `iston G, of the pump-cylindersF and plun- 'ers H, I do not here claim, and in lieuof be- 1g employedin pumping, lthe cylinderl't` and listen G might be employed to do otheruseul work.

K K designate two pipes which establish .ninterrupted communicationbetween the two nds of the cylinderA and the cylinder E, and hese pipesmay extend any reasonable distance nd through circuitous passages wherepower ould not be practically transmitted by rods r other mechanicaldevices. It' the two cylnders A and E are entirely iilled with water rother liquid, it will be readily understood hat when the piston G ismoving in the di! ection indicated by the arrow the water or liqlid willbe forced down the pipe K, moving he piston G and the pump-plunger-H inthe Lirection indicated by the arrow, and producing ,n upward current inthe pipe K', to lill the `ylinder A, behind or on the right ot' thepis-y on C. NVhen the piston C is moved toward he right lthe water willbe forced downward n the pipe K and upward in the pipe K, movng thepiston G and its attached plungers H oward the left. Thus it will beunderstood hat in whichever direction the piston G is noved the pressureexerted by it is transmited through the columns of water in the pipes iK, andthe piston G is moved simultaneousyin the opposite direction. Byinserting a ining in the cylinder D its power would be ncreased, but thepiston E would not then per- 'orm its whole stroke.

It is desirable that the two pistons G and G `li'ould both move inunison, or commence their ytroke together, and yet if, when theapparatus s started, the piston C commences its stroke vhile the pistonG is at the middle of its stroke, he piston C could only move until thepiston Sr reached the end of its stroke, and the appalatus would bestopped. To prevent this, and inable both pistons to come to a commonstartng-point, no matter at what point in their itroke they are started,I connect the two ends f the cylinder A by two passages, g, oneot' vhichis shown in section, and the flow ofliquid 'rom the ends of the cylinderthrough the pas- ;ages is controlled by pass-over valves h h', v'hichare weighted or loaded, so that during :he ordinary working of theapparatus theyA will not open. 1f we suppose that at the first itartingof the apparatus the piston C starts `'rom the position shown in Fig. lto move toward the right, while the piston G starts at )alf-stroke,thepiston O, as soon as the piston 3i ,reaches the end of its cylinder,will, create sufficient pressure to open the valve h, and thus )ermitthe passage of water around the piston C to the left-hand end of thecylinder A, and allow said piston to complete its stroke. The twopistons C and G will then commence their second stroke from the ends oftheir respective cylinders and terminate their strokes together.

It is intended to keep the cylinders A and E and the pipes K K alwaysfull of water; but as there will necessarily be some slight loss byleakage, I provide a reservoir, L, above the cylinder A, whichcommunicates with the passages G by pipes i, in which are check-val vesi', which will open to permit water or other liquid to pass from thereservoir L to the cylinder A, but will not permit liquid to pass fromsaid cylinder to said reservoir, thus compensating for any leakage.

In deep mines the rods for transmitting motion to pumps in the mine fromactuating mechanism at the surface are often of great length and weightand take up room in the shaft which cannot well be spared. By myinvention such ponderous connectionsare dispensed with-and the powertransmitted through the water-columns in an economical and effectivemanner.

1f desirable, diaphraglns might be substituted forthepistons G G and thechambers in which the diaphragms'are arranged connected by the pipes KK.`

What I claim as my invention, and desire to secure by Letters Patent,is-

l. The combination, with two liquid cylinders or chambers and -pistonsor diaphragms therein, of two pipes for establishing free communicationfrom the two ends of one cylinder or chamber to the two ends of theother cylinder or chamber, a motor for reciprocating one piston ordiaphragm, and a pump or pumps actuated by the other piston ordiaphragm, substantially as and for the purpose specified.

2. The combination, with two liquid cylinders or chambers, the two endsof one ot'which are connected by passages controlled by loaded pass-overvalves, and pistons or diaphragms in said cylinders or chambers, ofpipes establishing a free communication from the two ends of onecylinder or chamber to the two ends ot' the other cylinder or chamber,and a motor for reciprocating one piston or diaphragm,substantially asand for the purpose specited.

3. The combination, with two liquid cylinders Aor chambers and twopistons or diaphragms therein, of pipes for establishing freecommunication from the two ends of one cylinder or chamber to the twoends of the other cylinder or chamber, a liquid-supply reservoir, and avalve or valves which permit the passage of liquid from said reservoir`to one of said cylinders or chambers, and a motor for reciprocating oneot' said pistons or diaphragms, substantially as and for the purposespecified.
